Living things

  1. 1. THINK ABOUT -Why does the text say that Leeuwenhoek discovered a new world? -What is a microscope? -Did Leeuwenhoek really see worms in the water? -Was he impressed to see a drop of water under the microscope?A microscopic worldRound about 1700, a Dutchman, Anton Van Leeuwenhoek, examined a drop ofwater through a microscope. He discovered a new world, full of tiny creatures. Hewas the first man to describe them:“ I could clearly see masses of tiny, moving worms. The water seemed to be alive with them. Itwas the most wonderful thing I had ever seen in nature: thousands of tiny creatures movingabout, living together in a drop of water. It was a marvellous sight,” ANTON VAN LEEUWENHOEK Letter to the Royal Society of London
  2. 2. In this unit, we will…-Learn what cells are and what they are like.-Learn what unicellular and multicellular living things are.-Discover the levels of organisation of multicelullar living things.-Learn the name of the five kingdoms of living things.
  3. 3. LIVING THINGS:1.Living and non-living things2.Living thing: live processes3.Cells: unicellular, multicellular.4.How living things are organized5.Kingdoms
  4. 4. Rocks People Plants Animals -They are bornWind -They eat -They react to the environment -They grow Air -They reproduce -They die
  5. 5. Make sentences following the example: Example: Living things are born.1.(EAT)…………………………………………………………………………………2.(REACT)………………………………………………………………………………3.(GROW)………………………………………………………………………………4.(REPRODUCE)………………………………………………………………………5.(DIE)……………………………………………………………………………………
  6. 6. There are three basic life processes: - Nutrition: living thins eat food, which contains nutrients. These nutrients provide energy. - Sensitivity: Living things react to their environment. - Reproduction: Living things have offsprings. New living things replace the ones which die.
  7. 7. All the living things are made up of tiny units called cells. microscope Cells are like tiny sacks full ofThe microscope was liquid.

Most cells are solenses magnify the image small you can t see them with theof an object many times. naked eye. Cells are living things, they carry out the life processes of nutrition, reproduction and sensitivity.
  8. 8. Cells have three main parts: Membrane: is the covering around the cell. Nucleus: is the part which controls the cell. Cytoplasm: is between the nucleus and the membrane. ANIMAL AND PLANTS CELLS Plant cells also have a hard wall around the membrane. They have special organelles called chloroplasts to carry out photosynthesis.
  9. 9. Draw a cell and write its parts: Membrane nucleus Cytoplasm Wall Animal cell Plant cell
  10. 10. All the living things are made up of cells.Animals and plants are Other living things are made upformed by a large number of of a single cell. This living thingscells which are organised are found everywhere: in water,according to their functions. in soil, in the air and in ur bodies. However, you can only see them through a microscope. Multicellular: Unicellular:Living things made up of Living things made up of many cells. a single cell.
  11. 11. Tissues are made up of cells which work together. Organs are made up of tissues which work Muscle tissue together. Heart Systems are made up of organs which work together.An organism is a complete livingthing. Many systems worktogether in an organism. Allliving things are organism. All thesystems in an organism worktogether to keep a living thing Digestive systemhealthy.
  12. 12. Put the words in order from the simplest structure to the most complex estructure: TISSUE ORGANISM CELL ORGAN SYSTEM
  13. 13. Living things are classified into groups called kingdoms.THE ANIMAL KINGDOM-Animals are multicellular-They eat other living things-They can move from one place to another-They have a nervous system and sense organs-They react to stimuli.THE PLANT KINGDOM-Plants are multicellular-They use sunlight and substances from de soil to make their food-They cannot move-They don t have nervous system or sense organs. However, they react slowly to somestimuli.THE FUNGI KINGDOM-Most fungi are multicellular. A few are unicellular-They depend on other organism for food.-They can t move.
  14. 14. THE BACTERIA KINGDOM -Bacteria are the most abundant of all living things. -They can be found everywhere in the world. -They are the smallest living things. They are called microorganisms or microbes. -They are unicelullar. -Some of them are helpful, like the ones we use to make yogurt, cheese or bread. -Some are harmful, they can cause diseases.THE FIFTH KINGDOM -This kingdom is made up of all the living things that aren t included in the other kingdoms. -They can be unicellular or multicellular. -Protozoa are unicellular microbes that feed on other living things.
